Definitions

• This invention relates, generally, to a cassette for use with a cash dispensing machine in which stacks of banknotes are stored, and more particularly, it relates to an apparatus for automatically maintaining pressure at certain locations on the rear of a stack of banknotes so as to facilitate the dispensing of banknotes via pickers at the front end of the stack.
• the cash dispensing machines or Automated Teller Machines (ATMs) in use today generally use containers or currency cassettes in which stacks of currency are stored.
• one cassette holds a stack of one denomination of currency.
• the cassette When the cassette is installed in an ATM, its dispensing end is positioned therein to enable a "picker mechanism" in the ATM to "pick” the front sheet or bill from the stack of bills in the cassette as part of a cash dispensing operation.
• Most cassettes have a simple pusher plate located therein which is used to resiliently bias the stack of sheets towards the dispensing end of the cassette as bills are picked from the stack in normal cash dispensing operations by the ATM.
• the cassettes are also used in Teller Assist Currency Dispensers (TACDs) which facilitate the counting of currency to be dispensed by human tellers.
• TACDs Teller Assist Currency Dispensers
• the wedging problem is due, basically, to the way in which currencies are made.
• the embossing or printing may be heavier or more pronounced on one side or end of the note than on the other side or end.
• the variation or increase in thickness is slight for one bill or note, the variations accumulate rapidly when several hundred such bills are formed into a stack in the cassette. This results in the "wedging" problem mentioned (as shown in Fig. 1), in that one side, for example, of the rear of the stack is not pushed to ⁇ wards the dispensing end of the cassette by the asso ⁇ ciated pusher plate.
• One current method of alleviating the wedging problem mentioned is to alternate the orientation of the notes or bills as they are formed into a stack in the cassette. This method makes loading the cassettes more difficult and time consuming than loading without regard to orientation. If the process of alternating the orientation of the notes is forgotten, or done incorrectly, serious problems are created when a cassette so loaded is placed in an ATM, for example, because the "picker mechanism" associated with the ATM will fail to "pick" reliably the bills from the cassette.
• a cassette for use with a cash dispensing machine which machine has a picker assembly including first and second pickers for picking banknotes from said cassette when said cassette is positioned in operative engagement with said cash dispensing machine, said cassette including support means for holding a stack of banknotes in said cassette, and pusher means arranged to move said stack towards a dispensing end of the cassette as a first banknote at said dispensing end is removed by said picker assembly, characterized in that said pusher means includes first and second members arranged to contact the side of said stack remote from said dispensing end, and first and second coupling means for providing resilient coupling between a movable actuating member and said first and second members respectively, each of said coupling means including a universal joint.

• the bills are stacked on their long, lower edges, and the top.long edges of the bills are seen.
• Each of the -individual bills forming the stack 16 of bills has a greater thickness on the left side than on the right side thereof, in the example shown.
• the solid pressure plate assembly 18 does not push evenly across the rear of the stack 16 of bills, and a cur ⁇ rency wedge is formed at area 20.
• the currency wedge at area 20 means that the right side of the stack 16 is not pushed into operative engagement with the picker 22 on the right side of the picker assembly 14.
• the picker 24 on the left side of the picker assembly 14 and the picker 22 are used together to pick the first bill in the stack 16 and transfer it to a trans ⁇ port mechanism (not shown) associated with the ATM 10 to thereby dispense currency in a conventional, rou- • tine manner.
• the pickers 22 and 24 may be vacuum operated, for example, and if one of these pickers is not in operative contact with the first bill in the stack 16, a malfunction in the picking operation may occur. r-

• the cassette 26 is shown in operative engagement with an ATM 10 in Figs. 2 and 4.
• the cassette 26 includes a floor panel 28, side panels 30 and 32, end panel 34, a removable, cover panel 36, and a door panel 38 (Fig. 4).
• the door panel 38 is of the "garage door” type that is made of a plurality of hinged slats or panels like 38-1 and 38-2, for exam ⁇ ple.
• the door panel 38 usually closes the dispensing end of the cassette 26; however, when the cassette 26 is moved into operative engagement with the ATM 10, a door opener 40 on the ATM 10 coacts with the cassette 26 to move the door panel 38 under the support floor 42 as the cassette 26 is moved to the operative posi ⁇ tion shown in Fig. 4.
• the cassette 26 is guided and supported on guide rails, for example, which are shown schematically as support 44 in Fig. 4.

• interlocks coupled between the cassette 26 and the ATM 10 to prevent the cassette 26 from being removed from the ATM 10 while the door panel 38 is in the open position shown in Fig. 4; however, because the interlocks are conventional and are not important to an understanding of this invention, they are not shown.
• the bills in the stack 46 have their long lower edges supported on the support floor 42 when loaded into the cassette 26.
• the support floor 42 is comprised of panels 42-1 and 42-2 which are spaced from the floor panel 28 by spacers 48 and 50, (Fig. 3) and the panels 42-1 and 42-2 are also spaced from each other to permit a block 52 to be slidably mounted **
• the block 52 has aligned slots 54 and 56 therein to receive the panels 42-1 and 42-2, respectively.
• the block 52 is resiliently biased to the left, as viewed in Fig. 4, by tension springs 58 and 60.
• Tension spring 58 has one end thereof secured to a stud 62 that depends from the underside of block 52, and the length of the spring passes around a pulley 64 that is rotatably mounted on a stud that is secured to the floor panel 28.
• the remaining end of the spring 58 is secured to a stud 66 upstanding from the floor panel 28 as shown in Fig. 3.
• the spring 60 is similarly mounted around a pulley 68.
• the block 52 is resiliently biased to the left, as viewed in Fig. 4.
• the block 52 and the springs 58 and 60 are part of a means for moving the stack 46 of bills towards the dispensing end of the cassette 26; this moving means is designated generally as 70.
• the moving means 70 (Fig. 4) also includes a " ⁇ "-shaped actuating member 72 which has spaced, parallel, vertically-positioned plates 74 and 76 that are connected by the joining portion 78.
• the joining portion 78 is secured to the block 52 by fasteners 80.
• the plate 76 has a long finger 82 (Fig. 3) extending therefrom, and this finger 82 coacts with a detent 84 that is mounted on the side panel 32, as seen best in Fig. 4.
• the detent 84 extends along the length of the side panel 32, and the detent 84 has spaced, elongated slots like 86 and 88 therein to receive stationary, headed pins 90 and 91, respectively; this construction enables the detent 84 to move in the directions of double arrow 92 (Fig. 4) .
• the detent 84 is resiliently biased towards the floor panel 28 by a biasing mechanism shown schematically as a tension spring 94.
• the detent 84 has a plurality of detent teeth, each of which has an angled side 96 and an abutment side 98 as shown in Fig. 4.
• the stack 46 becomes smaller, and the " ⁇ "-shaped member 72 is moved to the-left (as viewed in Fig. 4) due to the urging of springs 58 and 60.
• the detent 84 is out of operative engagement with the finger 82 by means not important to an understanding of this invention; however, the detent 84 is shown in its lower or operative position in Fig. 4.
• the " ⁇ "-shaped member 72 "oscillates" slightly as bills are picked from the stack 46.
• the spring 94 pulls the detent 84 towards the floor panel 28 to enable one of the abutment sides, like 98, of the detent 84 to engage the finger 82 to provide an abut ⁇ ment for the " ⁇ "-shaped member 72.
• This construction maintains pressure on the stack 46 of bills in the cassette 26 during handling or transit of the cassette 26 from the associated bank or transit agent to an ATM 10 in which it is installed.
• the moving means 70 also includes a first member designated generally as 100 (Fig. 2); this member 100 is positioned between the plate 74 and the rear end of the stack 46 of bills, as shown in Fig. 2.
• the moving means 70 includes a second member 102 that is also positioned between the plate 74 and the rear end of the stack 46, as shown in Fig. 2.
• the function of the members 100 and 102 is to supply pressure to the rear of the stack 46 while accommodating stacks of bills that produce various currency wedges as previ ⁇ ously discussed in relation to Fig. 1.
• An important point to be stressed here is that there should be one member, like 100, for each picker, like 22.
• the member 100 should preferably be aligned in the cassette 26 so that it resiliently applies pressure towards its associated picker 22. Even though the stack 46 of bills forms a currency wedge as shown in Fig. 2, the first bill 104, shown as a line, is in firm contact with pickers 22 and 24 due to the pressure from members 100 and 102, respectively. This firm contact at each of the pickers 22 and 24 enables the first bill 104 in the stack 46 to be picked cleanly and also obviates the problems mentioned earlier.
• the cassette 26 has conventional restrainers (not shown) to restrain the dispensing end of the stack 46 of bills from moving to the left, as viewed in Fig. 2, while each first bill 104 is picked from the stack 46. The first bill 104 is then transferred by the picker assembly to transport mechanisms (not shown) associated with the ATM 10 for eventual dispensing to a customer of the ATM 10 in a conventional, routine, cash dispensing operation.
• the first and second members 100 and 102 alluded to are identical.
• the second member 102 (Figs. 2 and 4) includes a cylinder 106 having a flange 108 by which it is secured to the plate 74.
• the second member 102 is shown in cross-section in Fig. 2 to facilitate a showing thereof, with the viewing plane being through the center of the cylinder 106.
• a piston 110 is mounted in the cylinder 106 for reciprocal movement therein, with the rod of the piston 110 passing through the center of the cylinder 106.
• the piston 110 is biased to move away from the plate 74 by a compression spring 112 that is located within the cylinder 106 as shown.
• the second member 102 also includes a planar member 114 that has a ball and socket joint 116 se ⁇ cured thereto as shown.
• the end of the rod of piston 110 is secured to the ball 118 in the socket joint 116.
• the planar member 114 is free to move with respect to a plurality of axes which pass through a common point located at the center of the ball 118; this enables the planar member 114 to conform or adapt to the rear of the stack 46, due to the currency wedge problem mentioned, while the second member 102 resiliently biases the stack towards the picker 24.
• Another way of looking at the cooperation between the planar member 114 and its associated ball 118 is that a line such as dashed line 115 (Fig.
• the first member 100 is identical in construction to the second member 102 already described, and the member 100 includes a planar member 120, a ball and socket joint 122, a cylinder 124, a flange 125, a piston 126, and a spring 128.
• the first member 100 resiliently biases the stack 46 towards the picker 22.
• the cylinder 124 is positioned on the plate 74 so as to align the reciprocating movement of piston 126 with the associated picker 22.
• the springs 58 and 60 (Fig. 3) resiliently bias the block 52 to the left (as viewed in Fig. 4) thereby moving planar member 74 and the first and second members 100 and 102 to the left to maintain the proper operative relationship with the pickers 22 and 24.
• the first and second members 100 and 102 were made of metal in the preferred embodiment; however, other materials may be used in particular applications. While vacuum pickers 22 and 24 are discussed, the principles of this invention may be extended to machines using other forms of pickers.
